Recycling and upcycling "close the loop," allowing materials to return to the beginning of the cycle, which drastically reduces the need for new resource extraction. Why the "Life Cycle" View Matters

For some products, like a wooden chair, the footprint ends at delivery. For others, like a car or a washing machine, the biggest impact happens while the customer is using it. Energy efficiency during this phase is critical to the product's overall life cycle assessment (LCA). 5. End-of-Life: Disposal vs. Circularity What happens when a product is done?

Releases stored carbon back into the atmosphere.

Once a product is finished, it travels. Whether by cargo ship, plane, or semi-truck, the global supply chain is a massive contributor to the total footprint. The "miles per product" metric is a key focus for companies looking to localize production and reduce their logistics impact. 4. The Product Use Phase

If we only measure what happens inside the factory, we miss the bigger picture. By using , industries can identify "hotspots"—the specific stages where emissions are highest—and innovate where it counts most.

The cycle starts in the ground. Mining raw materials, logging timber, or extracting fossil fuels is energy-intensive. Heavy machinery and transportation at this stage often rely on high-emission fuels, creating a significant "carbon debt" before a single part is even made. 2. Manufacturing and Processing
